UNITED-i STATES PATENT OFFICE.

JOHN QUINCY ADAMS, OF WEST UNION, IOWA.

Application filed January 13, 1908.

To all whom it may concern:

Be it known that I, JOHN QUINCY ADAMS, a citizen of the United States,residing at West Union, in the county of Fayette and State of Iowa, haveinvented certain new and useful Improvements in Rotary Engines, of whichthe following is a specification.

This invention relates to rotary steam engines, and has for an object toprovide an engine of this character which may be run at a maximum rateof speed with a minimum expenditure of fuel.

A further object of this invention is to provide an engine of thischaracter which will be simple in its structure, and which will occupybut small floor space.

A further object of this invention is to provide an engine of thischaracter in which a head is located within a stationary cylinder, thehead having live steam passages and arranged to deliver steam against aninner impact surface formed upon the inner periphery of the stationarycylinder, and thus produce a rotary movement of the head within thecylinder.

Other objects and advantages will be apparent from the followingdescription and it will be understood that changes in the specificstructure shown and described may be made within the scope of the claimswithout departing from the spirit of the invention.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the sev eral views,Figure 1 is a side elevational view of the present engine, Fig. 2 is anend elevational view, Fig. 8 is a side elevational view showing one sideof the casing removed, Fig. 4 is a vertical longitudinal sectional viewon the line 44 of Fig. 2, Fig. 5 is a vertical cross sectional view onthe line 5-5 of Fig. 1.

Referring now more particularly to the drawings, there is shown anengine 10 consisting of a rotary wheel or head 11, having a lateral hub12 at one side, as shown. The hub is thus arranged to receive a shaft 13keyed to the hub as at 14. The wheel opposite the hub 12 is providedwith a similar hub 15 and this hub is provided with a cavity 16 and thusserves as a steam inlet.

The wheel or head 11 is provided with a plurality of radial pipes 17,four being shown in the drawings and at the center these pipes are incommunication with the steam inlet cavity 16. At the outer ends, thesepipes are connected with short pipes 18. which ex- Specification ofLetters Patent.

Serial No. 410,628.

tend at right angles to the pipes 17 which open outwardly of the wheelor head 1 1. Located beneath the pipes 18, there are shown similar pipes19 which also open outwardly of the head 11, as shown. The pipes 19 areprovided with lateral passages 20 for a purpose to behereinafterdescribed. This construction thus provides a perfectly smooth peripheralbearing edge with the pipes 18 and 19 respectively opening to itssurface.

The wheel 01' head is disposed within a cas ing 21 which is preferablyin the form of a ring, as shown, and this casing is provided at itslower end with flanges 12 and 13 respectively by means of which theengine may be bolted upon a suitable flooring. The casing is provided onits inner periphery With substantially V shaped teeth or corrugations15, and these teeth or corrugations are thus arranged to extend towardthe wheel or head 11 with their points clearing the wheel, as shown.

The casing is provided with washer plates 22 and 23 respectively, andthese plates are of a width to cover the casing 21 and the depth of theteeth 15, and connected with the washer plates 22 and 23 respectively,there are shown, side plates 24 and 25 respectively provided to completethe casing described and the plate 24 is provided with a passage at itscenter to receive a steam inlet pipe 25. The inlet pipe 25 is secured tothe plate 24 by a collar 26 bolted as at 27 to the plate. The inlet pipeis thus in communication with the cavity 16. The plate 24 is providedwith a passage 28 disposed over the hub 12, as shown. The outer edges ofthe plates 24 and 25 respectively are bolted together, through the thickpart of the teeth 15.

Secured upon the plate 24, there is shown a half pipe 29, and the openside of this pipe is in communication with the passages 20 formed in thepipes 19. The pipe 29 is provided with an exhaust outlet pipe 80. TheWheel or head 11 is provided with packing rings 31, and the steam inletpipe is provided the steam has been spent, it will pass to the pipes 19,and exhaust through the ports 20 to be discharged through the pipe 30,as is obvious.

WVhat is claimed is:

1. In a rotary engine, the combination with a stationary annular casinghaving steam impact teeth on its inner periphery, plates bolted to thesides of said casing, one of said plates having an annular chamberopening within the casing, of a piston revolubly mounted with in thecasing and hav ing a plurality of angular steam inlet passages openingon the impact teeth, said piston having a plurality of exhaust portslocated adjacent the outer ends of said passages and opening into theannular chamber, a steam exhaust pipe connected with the annular chamberand a source of steam supply connected with the annular passages.

2. A rotary engine comprising a stationary annular casing having steamimpact teeth on its inner periphery, a revoluble piston located withinthe casing, plates bolted to the sides of said casing, one of saidplates having an annular chamber opening on the piston, said pistonhaving a plurality of radially disposed steam inlet passages opening onthe impact teeth, said piston having a plurality of exhaust portslocated adjacent the outer ends of said steam inlet passages and openingonto the teeth and. into the annular chamber respectively, a steamexhaust pipe connected with said annular chamber, and a source of steamsupply connected with said steam inlet passages.

In testimony whereof I afl'ix my signa' ture, in presence of twowitnesses.
